HP-UX Support

With HP-UX’s end-of-life looming (end of 2025), we want to remind everyone that Allegro supports HP-UX! Just like with MPE, your HP-UX systems will keep running even after end-of-life (EOL) is reached. If you’re not ready to migrate off, please contact us so we can discuss how Allegro can help you keep your HP-UX and MPE systems running! If you are ready to migrate, we can help with that too. We can be reached via our website (, or email (, or by phone (+1 408-252-2330).

Allegro also writes mobile apps

Allegro develops apps for iOS, Android, Mac, and Windows.  Our most recent mobile app reads barcodes and QR codes, takes photographs, and uploads them to a web server to provide the customer with the fastest field-to-user data in their industry.

Charon and SIMH tape images

Allegro has the exclusive ability to directly generate Charon-format NM STORE tape image files and SIMH-format CM STORE tapes image files.  Differing from STORE-to-disk format, these can be useful when moving files or data from one HP 3000 to an emulated HP 3000 when STORE-to-disk files aren’t appropriate.  Please contact Allegro for further information.

Enhancing old programs

Allegro is pleased to announce “we still have it”. We recently added functionality to several older MPE/iX programs with a combination of XLs and patches. If you are looking for new functionality, please contact us!

New versions of KNOCKOUT and BOUNCE

We’re pleased to release updated versions of our KNOCKOUT product, and the free subset, BOUNCE.

Allegro offers…


To real problems. Your problems. We provide customers with better-than-OEM support services, managed services, products, and expertise. Making hard problems go away is what we do every day. Let us show you how we can solve issues facing your business today.


We offer new recurring revenue sources to our service partners through innovative support service packages that add value to their existing offerings while making their own operations easier and less labor intensive. Customers get the benefits of new and better assistance services, delivered by people who have many years of experience in real-world customer environments and who understand their needs.


When we started all this, in 1984, the industry was at the height of the proprietary operating system era when vertical market applications and customized solutions were the norm. In today’s age of “open systems“, many don’t know how smooth IT operations can be when you have tools that are built for the express purpose of making your business run. But we remember those days and our people carry forward the ideals of those times while applying them to today’s modern IT ecosystems.


From business best practices developed over many years and across many computing platforms, to system internals, compiler and kernel development, education and training, we have been addressing our customers’ critical business needs for decades.
